Hepatic fibrosis is a wound healing process of the liver, which is characterized by overproduction and accumulation of extracellular matrix. Hepatic fibrosis occurs when chronic inflammation causes a deposition of scar tissue. Dimethylnitrosamine (DMN) is a potent liver toxin that can lead to fibrosis of the liver. DMN causes massive hepatocyte damage, cell death by necrosis or apoptosis and liver tissue distribution. Citrus unshiu, which is known to contain several flavonoids, has pharmacological effects on anti-oxidative, anti-cancer, anti-microviral and anti-inflammation activity. Therefore, we investigated the effect of premature C. unshiu and fermented premature C. unshiu extract on DMN-induced hepatic fibrosis mouse model. Here, we show that administration of premature C. unshiu and fermented premature C. unshiu reduces the generation of triglyceride, alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA) and cytochrome P450 2E1 (CYP2E1) in mouse serum. Also, the extract reduced the mRNA expression of glutathione S-transferases (GSTs), Heme oxygenase-1 (HO-1), NAD(P)H quinone oxidoreductase 1 (NQO1), and increased inflammatory factors such as IL-6, COX-2 and iNOS. These results suggest that premature C. unshiu has anti-hepatic fibrosis activity by regulating metabolic detoxification pathways such as cytochrome P450s and GSTs.
